C# COM Interop Creating New Excel Workbook

Question

I am using Microsoft.Office.Interop.Excel in a C# winform but I can't figure out how to create a new Excel workbook. I have tried everything in the documentation but I get nothing but errors. Workbook wb = new Workbook() compiles just fine but throws an incomprehensible runtime error.

Answer 1

You are probably getting the same error as you would get if you tried to instantiate a Workbook in Excel VBA using

Dim w As Workbook
Set w = New Workbook

Try instantiating the Application object, then call the Application.Workbooks.Add method. It takes an optional parameter, which is the name of a template.
